Chemical Guys CWS20816 Watermelon Snow Foam Car Wash Soap, (Works with Foam Cannons, Foam Guns or Bucket Washes) Safe for Cars, Trucks, Motorcycles, RVs & More, 16 fl oz, Watermelon Scent

First time user, and I am pleased with the results. Used around 3oz of soap, and about 16oz of water per car. Leaves a great shine. Still had to use a hand mitt to get everything. Would buy again.

Had great expectations for this car wash but sadly ended up terribly disappointed. While I'm familiar with the Chemical Guys good name and reputation, this was in fact my first product purchase in which to evaluate one of their famed products. I was sold by the "Watermelon" as I love that scent and figured it would help me enjoy washing the car. However, having read the reviews that state it is great smelling to over-powering strong, I hate to report my particular bottle had little to NO scent accompanying it? Maybe they toned it down after complaints of being too powerful? Oddly, when I opened the bottle to sniff the scent, it was rather muted and bland - I figured it must develop it's scent with water dilution. But, no, no such watermelon scent ever developed. OH, well, I bought it to use with my foam cannon to clean the car so what if it was not smelling pretty. Well, I'm even more disappointed to say it didn't perform well at all in it's cleaning function either, actually, it left a nasty, mottled film/stain on the car. I even am particularly careful and only foamed sections of the car at a time in order to get them rinsed well without extended exposure to the soap. Using my power washer the car received a copious rinsing. To my dismay, as I finished and dried the car I could see a mottled haze-film staining left by the soap. I re-rinsed, scrubbed, but to no avail. It was embedded in the surface. I fear it will take a few passes in a car wash and some time before, hopefully, it releases from the paints surface. Fortunately I have a white car so in bright sunlight it's not quite so noticeable, but in shade it was very apparent. Also, on the windows surfaces I noted microscopic "white dots" that clung to the windows after washing? I literally had to take a credit card and scrape them off the windows. Odd. I used merely 1.5 ounces and warm water as directed and while it indeed foamed beautifully, the job it did was totally unacceptable. Obviously not what I was expecting. Reading reviews later, which I wanted not to believe upfront, I did note several complaints of the very same staining, residue issue. Maybe it's certain batches? Highly disappointed and much work ahead for me on my next wash attempting to remedy the surface stains.

I use this as a pre-wash soak if the cars are dirty. It's not always necessary but if the car is really nasty, I'll blast it with this and just let it sit for a while and then spray that off and then follow up with my typical foam wash/mitt rinse. Does it work? Great question. I'm not actually sure. I know it probably doesn't hurt though and my 6 year old gets a kick out of blasting the cars with foam so I guess at least it's worth it for the entertainment value.

Versatile wash liquid that smells amazing. The color is nice and creates a thick foam. Rinses easily for streak free shine and finish. Chemical guys create a versatile performing product !

This snow foam works pretty well in my foam cannon but the only reason I gave it a try was because it was a lightning deal and needed a small bottle to try out in a few different cannons. This company is great at marketing and that is why they are successful (props to them) but most of their products are sub-par. I can say that this is one of their better products that I have tried. I will not be purchasing it again though.
